In April 2023, the TV star revealed her diagnosis of stage 4 triple-negative breast cancer.

Lizzy Musi also known as Lizzy Mussey, a race car driver known for her role on the Discovery Channel's "Street Outlaws: No Prep Kings," has passed away just over a year after being diagnosed with stage 4 triple-negative breast cancer. She was 33.

Musi died on June 27 at her North Carolina home, surrounded by her family, as her father, fellow street racer Pat Musi, shared on Facebook.

Lizzy Musi first shared her cancer diagnosis on Instagram in April 2023.

"Hey Everyone, I haven’t been able to have much time to post due to an unexpected life change. A few days ago, I was diagnosed with Triple Negative Stage 4 Breast Cancer that has spread from my lymph nodes to my liver," she wrote.

“I have a rough journey ahead of me. I appreciate everyone’s messages and calls,” she added.

Triple-negative breast cancer (TNBC) is a particularly aggressive form of invasive breast cancer that grows and spreads rapidly, according to the American Cancer Society.

Musi continued to update her followers on social media. In June 2023, she posted a photo on Instagram showing her with a shaved head, explaining that she decided to shave her head due to “extreme hair loss.”

“Well here is the new me ... some days are tough to look in the mirror, but there are days where I feel stronger than ever,” she wrote.

In April 2024, Musi shared in a Facebook video how her diagnosis had changed her life. The video showed her undergoing various treatments at a hospital.

“I am so very thankful for what this journey has actually taught me. I now know I have a purpose in life. I am grateful to keep going,” she told her fans.

A longtime street racer, Musi also appeared on "Street Outlaws" spin-offs "Locals Only," "Gone Girl," and "Fastest in America." She made history in 2014 as the first woman to win a Pro Nitrous national event at the Professional Drag Racers Association U.S. Drags, according to her official website.

In 2023, she became the first female driver to win an event on "Street Outlaws: No Prep Kings."

Musi's final Instagram post featured a photo of red roses in a hospital room. She tagged her location as Medias Klinikum Burghausen, a cancer treatment facility in Germany.

"Thank you so much for the beautiful flowers Mikey!!" she captioned the shot. "Made my morning on top of great news this morning!!"
